Whey Espresso

Add 5gm of coffee or more if you like it strong in 200ml boiling water and prepare the coffee

Mix 1/2 scoop of whey in a shaker in a 50ml water (Luke warm or cold water only) and pour into coffee

For foam, blend or shake again. Be careful because when you shake hot water or coffee in shaker it will spill. I used a electric blender/shaker
